Waveshare DVK512 Raspberry Pi Expansion Board Previous 
The Waveshare Raspberry Pi High-Precision AD/DA Expansion Board adds AD/DA functionality to Raspberry Pi expansion projects. It provides analog-to-digital and digital-to-analog interfaces for electronics and robotics development. The board uses a standard Raspberry Pi 40PIN GPIO extension header and supports Raspberry Pi series boards and Jetson Nano. It includes an onboard ADS1256 24-bit ADC with 8 channels and a 30ksps sampling rate. It also includes an onboard DAC8552 16-bit DAC with 2 channels. The board is designed with input and output connection options for analog and digital signals.
